is there a technical way to block a customer?

Hello,

If you have a serial-refunder concern, can you block that person's credit card from ever successfully transacting with your site in the future?

I was wondering if you can set up the equivalent of a block/ban list in Authorize.net.

Kind of like how you can set up a spam filter with e-mail, where all future communications from a specified email address get sent to the junk folder.

    Yeah, though you'd probably have to get it done through tech support and they can block the IP. I remember we went through this back in the day and it took a couple of phone calls and several times getting transferred to a couple of different departments but we got it done. It's really not worth it unless you're losing a LOT of money to this person though and unless you have a bunch of different products the same person is ordering/refunding, I can't see it being worth it.

      thanks,

      so it's more of an i.p. address block than the credit card number block? an i.p. address is reasonably good, but the credit card number block is even better. that way if they use a different i.p. address, they still get blocked.

      i would think a credit card processor would be fine with you blocking someone. they don't want chargebacks, fraud and hassles any more than the vendor does. so if the vendor is able to spot a problematical customer, giving the vendor the tools to block that person would only make things better for both the vendor and the gateway/merchant account.

        You need to ask the processor about CC block. Problem with CC block is they may have more than one. If they can block the address, that might be better but every one in the ZIP code (if us) may get blocked. You have to ask, if they will tell you.

        You can block an IP in most hosting control panels. Blocking an IP address can be a big problem though. Many IPs are pooled/shared. I hate those because I get blocked from sites because their is a spammer on the Network (Philippines) and when my IP gets blocked hundreds of thousands get blocked. Everyone on my island (a large one) is blocked. Not good for traffic or sales.

        Some block the Philippines because there is high fraud. I'm not Filipino.
